Resolved! Input capture interrupts not fired on STM32F401
Hello,I have configured a CUBE IDE project to match a Nucleo-F401RE board to measure the system clock pulses (at 84MHz) between to consecutive rising edges of an external signal applied to pin PA3 (which is Timer2 Channel4 input).The Input Capture in...
How VDDA, VDD, Vref+ effects ADC value?
Hi guys.I am using STM32F401VEH6 to read the peak value of a waveform like sinewave.but the value drifts about 40LSB time to time.I connected VDDA to Vref+ and seperated from VDD.(based on Application Note recomandation)But when I checked the datashe...
Resolved! Internal RAM: Potential Issues when using a large percentage of RAM
Hello,I am using the STM32F756ZGT6 for an upcoming project. I am using a 480x272 resolution display (RGB565) with a single layer. I also have additional features that will be on this board that use more RAM (2 tasks, multiple variables, etc.) that a...
Resolved! Do .bin files use relative or absolute addresses?
I am trying to set up a dual boot system using a bootloader in stm32F7 without using the dual bank operation. I have the bootloader, which can flash the bin files directly to the flash .My concern is whether .bin files contain any address information...
Statemachine or Statechart implentation in C
Does anyone know the best way to implement a statechart or statemachine in C? Are there specific libraries required or should I consider just using simple statemachine tables with switch statements? Maybe statechart is overkill for my app and using...
Resolved! Runt Pulse Issue on SPI MOSI
Hello,I'm trying to do a basic spi master transmit, and am having issues with the MOSI pin output. It seems the value is getting written, but the voltage swing is ~200mV rather than full value. I suspect I have the GPIO pin mis-configured, but I'm at...
Project with UART Rx in DMA interrupt mode and two timers timer 6 and 7 configured for interrupts. Not getting data using STM32F446RE nucleo Board
I have written a code to receive UART data in DMA interrupt mode using circular buffer and configured timer 6 and timer 7 for doing other tasks in the same code. The problem I am facing is that I am not getting UART data and neither timer interrupts ...
Resolved! Once in a while STM32F446 is unable to drive pin PA0 high or low
I'm working with the STM32F446-microcontroller and once in a while after power-up the microcontroller is unable to drive pin PA0 high or low and I also suspect that it can't drive PA8, configured as an I2C-clock, either when this problem occurs. Ther...
